After being shown the volleyball, Shiori and Chika followed the two men to a corner of the beach. Lines were drawn in the sand to create a rectangular court. Inside this makeshift, simple volleyball court, divided by a net in the middle, stood Shiori, Chika, and the two men.

"Okay, let me reiterate: the match is beach volleyball," one of the men announced. "First to reach ten points wins a set. First to win two sets wins the match. ...By the way, are you familiar with the rules of volleyball?"

He shrugged. "Well, this isn’t an official match or anything. You score one point if you drop the ball into the opponent’s territory. If the ball goes out of bounds, the last person to touch it is out. The same player shouldn’t touch the ball twice in a row. The team that scores gets to serve next. You can use your hands, your feet, or any part of your body."

He glanced at them. "...I guess that’s about it. What do you think? Did you understand? Should I explain it again?"

"No, I understand the rules. It’s fine," Shiori said.

"Yeah, I know. It’s okay," Chika added.

"First to ten points per set, and you win if you take two sets... This looks like it’s going to be a pretty long match," Shiori murmured.

"This is a normal, serious beach volleyball match," the man said, holding the volleyball.

As he gave his brief explanation, Shiori and Chika nodded in response, inwardly bracing themselves for what seemed like a long contest.

Other men began gathering around the court.

"Hey! I heard that Range and Talc are playing beach volleyball against some really beautiful sisters!"

"Oh... nice. Let’s watch carefully."

"Let’s bet on who wins. I’m putting my money on those gorgeous ladies."

"Then I’ll go with Range and the others."

"I wonder if there’ll be any accidental swimsuit slips. Hehe."

"Hey, that girl has huge boobs. I wish she’d take off her hoodie."

"The other one has long arms and legs and an amazing figure... She’s incredible. So beautiful. I like her."

"Uh..."

"Uh..."

The men were excited to see the beautiful Shiori and Chika playing beach volleyball. They settled into spectator mode, drinks in hand, as the court became surrounded. Shiori and Chika shivered under the excited, lecherous gazes directed at them from all directions.

Then their opponents—the men the spectators called "Range" and "Talc"—spoke to them.

"It’s really lively here. Everyone’s fallen for your beauty and style," Range said with a grin.

"Heh heh... Okay, let’s get started then," Talc added. "First team to ten points wins. I’m the one who asked you to play, so I’ll let you serve first."

"Understood," Shiori replied.

Watching the excitement of the men around him, Range grinned and smoothly handed the volleyball to Shiori.

"Chika, which of us wants to serve?" Shiori asked.

"...Honestly, I’m not very good at it, so please go ahead, big sister."

"Okay, I understand. I’ll do it."

After a brief discussion, Shiori took the volleyball and moved to the back of the court. Seeing this, Range and the others lowered their stances and raised both hands.

"Phew... hah!"

Watching Range’s movements, Shiori took a deep breath, composed herself, tossed the ball upward, and flicked it with her hand.

"Here it comes..."

"Hey...! Come on!"

"Heh heh, I’ll go easy on you at first... Here we go!"

The volleyball arced straight toward the center of Range and Talc’s territory. Talc caught it firmly with both hands. Range then hit the ball with a gentle bounce and sent it upward with both hands. With a sly grin, Talc lightly flicked it back toward Shiori and Chika.

"Ah! Chika...!"

"Mmm...! Ah...!"

"Ohhh...!"

"Her breasts got in the way!"

"Oh, so erotic...!"

The ball flew straight toward Chika. She raised both hands to catch it, but her chest seemed to interfere, and the ball shot off in a completely different direction.

"Ugh...! Argh!"

"Big sister! Uh... ah...!"

"Oh...!"

"Nice save!"

"That’s great!"

"Those boobs are amazing!"

Shiori reacted instantly. For a moment she seemed to stumble, then she leaped forward, scraping her body against the sand as she sent the ball back upward. The watching men cheered in excitement.

Chika tried to jump and flick the ball toward the opponent’s side, but she tripped and stumbled. She frantically waved her hand, sending the ball back like a weak toss.

"Wow... that’s soft."

"If you keep playing like that, I’ll attack!"

"Ah! Ah, ugh...."

"Ah, ahhh...!"

Such a light toss wouldn’t work. The ball was easily returned, and the opponents scored with an attack.

"Yes! One point!"

"Heh heh, we scored first!"

Range and Talc rejoiced. Shiori and Chika stood up, their faces slightly furrowed, and lowered their gazes toward the sandy beach.

"Ah...! I’m sorry, big sister..." Chika said.

"Well... it’s tough if you’re not used to this," Shiori replied.

Yes, the sandy beach. Both Shiori and Chika had some experience playing volleyball in physical education classes, but that had been on a hard, solid gym floor. Neither had ever played on sand—an environment where you couldn’t get proper footing. In fact, they had barely even walked on a sandy beach before. Walking was one thing, but quick movements or jumping to launch attacks? That was another matter entirely.

"Heh heh... looks like it’s tough for you," Range said.

"Come on, try harder. If you keep going like that, we’ll take two sets first," Talc added.

On the other hand, the opponents seemed accustomed to moving on the sand. They moved with ease.

"Uh... uh, uh..."

"Uhh..."

"This... in a way, it looks like it’s going to be a tougher fight than a normal one... hehe, that’s good ♡" Shiori thought to herself.

"I might lose in straight sets... ♡" Chika thought.

Outwardly, Shiori and Chika wore expressions of frustration, but inwardly, they were beginning to feel excited about the beach volleyball match—knowing it would be a hard-fought battle.
